About the Bcrypt Generator & Verifier

Storing passwords as plain text is risky — anyone who sees the stored data sees the passwords. Bcrypt solves this by converting each password into a scrambled, one-way code that can be safely stored. This tool creates those codes for you and lets you confirm whether a password matches an existing one. It's handy for setting up seed accounts, testing logins, checking a saved code, or simply learning how password protection works. Everything runs on your own device — nothing is uploaded.

Use the Generate tab to turn a password into a storable code, then copy it into your app or database.

Use the Verify tab to check a password against a code you already have — great for debugging a login.

A strength of 10–12 is a good balance of speed and safety for most projects in 2026.

The same password produces different-looking codes each time — that's expected, and every one still verifies correctly.

How it works

Three steps. No sign-up, no upload, no wait.

Pick a mode

Choose Generate to protect a password, or Verify to check one against a saved code.

Type your text

Enter the password or phrase. For Generate, set the strength slider to taste.

Copy or check

Copy the generated code, or see an instant match / no-match result — all on your device.

Frequently Asked Questions

What is bcrypt used for? ▼

Bcrypt turns a password into a scrambled, one-way code (a hash) that websites and apps store instead of the real password. Even if that stored code leaks, the original password can't simply be read back out of it. This tool lets you create those codes and check whether a password matches one.

What does the strength (cost) setting do? ▼

The strength — also called the cost factor or rounds — controls how much work goes into building each code. Every step up roughly doubles the effort, which makes the code slower and far harder for an attacker to crack by guessing. A value of 10 is a common, well-balanced default; higher is more secure but takes longer to compute.

Can a bcrypt code be reversed back into the password? ▼

No. Bcrypt is a one-way process, so there is no button that turns a code back into the original password. The only way to test a password is to run it through the same process and compare — which is exactly what the Verify tab does.

Why do two codes for the same password look different? ▼

Bcrypt mixes in a random salt each time, so hashing the same password twice produces two different-looking codes. Both are still valid — the Verify tab will confirm the password matches either one. The salt is stored inside the code itself, so no extra bookkeeping is needed.

Is my password sent anywhere? ▼

No. Everything happens right here in your browser — the password and the code are never uploaded, logged, or transmitted. Nothing leaves your device.

What's a safe strength to choose? ▼

For most uses, 10 to 12 is a solid range in 2026. Lower values (4–9) compute almost instantly but offer less protection; higher values take noticeably longer, especially in a browser, so this tool caps the strength at 12 to keep the page responsive.
